Question

What is direct and indirect band gap semiconductor

Answer 1

In semiconductor physics, the band gap of a semiconductor is of two types, a direct band gap and an indirect band gap. ... In an "indirect" gap, a photon cannot be emitted because the electron must pass through an intermediate state and transfer momentum to the crystal lattice.
